Combat/Anti-Installation
Installations are an enemy-type representing "land-based installations", and are characterized by high armor and high HP. They are difficult to handle using normal anti-ship setups and require specific setups in order to be destroyed. Installations are typically found as bosses or as boss escorts.
General Characteristics
- Installations cannot perform or benefit from flagship protection.
- They have different damage statuses instead of the normal ones used for ships.
- These statuses are merely cosmetic in nature and have no gameplay difference.
Ship Damage Label | Installation Damage Label |
---|---|
Lightly Damaged (小破) |
Confused (混乱) |
Moderately Damaged (中破) |
Damaged (損害) |
Heavily Damaged (大破) |
Broken (損壊) |
Sunk (撃沈) |
Destroyed (破壊) |
Installation Classification
Installations are classified by two categories: Ship Type (BB, BBV, or CV) and Toughness (Soft Skin or Hard Skin).
Installations Glossary
Here is a list of all "Installation type Abyssals" ever encountered in the game.
- Are listed the base forms of those installations, most coming in many variations often depending on the map difficulty, the map state (last-dance), and the event itself (most events bringing new variations).
- Some installation sub-forms of interest are also listed, those forms having special variations like a different type than the main form, of some special abilities.
- Note that some toughness characterization may be erroneous, since most of those installations were introduced before this system was defined.
- Some event-only installations might not fall in one of these categories.

- Notes
- The Northernmost Landing Princess is not immune to the Torpedo stat.
- This means that during a Night Battles, the full "Night Battle Power" is used to calculate damage against her.
- She is still immune to torpedo-based attacks, which does not include airstrikes.
- The Harbour Water Demon cannot attack during day battles when "moderately damaged" (like carriers).
- Standard Night Battle rules still apply (she can attack even if moderately damaged).
- Supply Depot Princesses have extra "Post-Cap modifiers", and can launch torpedo attacks.
Attack Behavior
The targeting of installation follow some special rules.
Support Expedition
- Shelling Support expedition can attack installations.
- It's unknown if torpedo support and ASW support will target installations or not.
Air strike
- Air strikes can attack installations normally.
Shelling
Carriers can only attack installations if equipped with at least one anti-installation Dive Bombers with non-zero slot, or if equipped with only torpedo bombers (no dive bombers or jets).
- Carriers equipped with no anti-installation Dive Bombers and at least one Normal dive bomber or jet with non-zero slot can not attack installations.
Dive-Bombers that can attack installations | |||
---|---|---|---|
Carriers will only attack installations in the shelling phase if equipped with Torpedo Bombers or Anti-Installation Dive Bombers.
| |||
AAR AAR AAR |
Submarines can only attack installations during the shelling if equipped with Amphibious Vehicles.
- They will only target installations during the shelling phases.
- They will be able to attack installations at night regardless of equipment.
- Their low firepower makes them poor anti-installation ships.
Carriers are unable to perform CVCI on installations, even if equipped with anti-installation dive bombers.
- Ise-class Kai Ni can still perform the Suisei-CI against installations.
"LST" type ships (No.101 Transport Ship so far) will focus on installations if any are present.
Special Attacks behave like normal against installation.
In general, using dedicated "Landing Equipment" or other "Anti-Installation Equipment" is recommended to deal the most dame against installations:
Torpedo
Opening Torpedo Salvos, Closing Torpedo Salvos, and Torpedo-based Cut-ins (like the TCI) cannot target installations.
- Those attacks will fail to trigger if only installation targets remain.
Night Battle
- The Torpedo stat is ignored when calculating night battle damage against installations. Please see Night Battle for more details.
- This makes destroyers, light cruisers, and heavy cruisers much weaker unless equipped with anti-installation equipment.
- When targeting installation the Cut-in choice will ignore any equipped torpedo.
- This means a ship with 2 mains guns + 1 torpedo, which would normally perform Mixed Torpedo Cut-in on surface targets, would perform Double Attack on installations instead.
- Exception for any DD Cut-ins: If the attacker has a main gun equipped, they can activate DD Cut-ins on installations, even if the main gun is not part of the cut-in's prerequisites (torpedo stat is still considered equal to 0).
- Night shelling Carrier Attacks will deal damage like they would to ships.
- This include Ark Royal's night swordfish attack.
- Air night attacks ignore all anti-installation bonus
- The attack can target installations even if no anti-installation dive bombers is equipped
Barrage Balloon
Barrage Balloons can be deployed in certain situations during day battles.
- Barrage Balloons can only be deployed on certain combat nodes with Installations

- Once deployed
- For every ship with a balloon equipped will boost the damage of the fleet and the LBAS (post-cap):
Balloon Effects | |||
---|---|---|---|
1 | 2 | 3 | |
Allied Day Shelling Damage | |||
Allied balloons [6] | 1.02 | 1.04 | 1.06 |
Allied LBAS Damage | |||
Allied balloons [7] | 1.02 | 1.04 | 1.06 |
Enemy balloons [8] | 0.95 | 0.90 | 0.85 |
- The effect stacks up to 3 balloons, and up to 1 balloon per ship,
- The effect applies to LBAS and day shelling, with the enemy balloons also negatively affecting allied LBAS,
- The effect does not apply to torpedo phases or night battles,
- If the ship deploying it is sunk, the balloon is then removed, as well as its effects.
Damage Calculation
- During day, damage is capped at 220 so any ship with a proper anti-installation setup will be able to hit the cap.
- When facing hard-skinned installations, it is better for battleships to have AP shells instead of Type 3 because they will hit the day cap anyway.
- Anti-installation is very important during night battle when the cap is raised to 360.
- Torpedo stat is always counted as 0 when attacking installations. This applies to both airstrikes and night battles.
- However improvements that provide damage during Night Battle is taken into account during such.
- Supply Depot Princess is the only known installation that takes post-cap damage from anti-installation equipment.
- This makes her vulnerable to getting one shot by nuke setups. See here for details.
- While dive bombers have a post-cap bonus during the air-strike, the low base damage means it is of limited effectiveness against high armor installations.
- The Armor Piercing modifier (post-cap) is effective against installation.
Calculation
Installations generally have a lot of HP and/or armor. But multiple different cumulative bonuses exist against them, allowing for massive damage when using the right set-ups. These bonuses are divided into 5 groups and are calculated in the following order[1]:
- Ship type bonuses
- General multiplicative bonuses
- Specific equipment bonuses:
- 11th regiment bonuses
- M4A1 bonuses
- Ho-Ni bonuses
- Landing craft synergy bonuses
- General Flat bonuses
- Post-cap bonuses against Supply Depot Princess
- Airstrike and Land Base special cases
- "Installation-like warships" special cases
- The bonuses' exact order is still under investigation and may be subject to changes.

- Notes
- A Landing Craft might be required to be equipped on the attacking ship for this bonus to be applied.
- As it is the only post-cap bonus common to all installations, it has a great potential.
- Due to the limited nature of Rations, this bonus is mostly "Pay To Win", and so is not recommended.
Airstrike and Land Base Bonus
For the damage formula, please refer to the LBAS and airstrike page. The multiplier is chosen randomly between two values. The chance is roughly 50%.
There are exceptions:
- For Torpedo Bomber:
- For Jets
:- There are inconsistencies with the bonuses.
- For the Land-Based Heavy Bombers
:- Could have a higher modifier than other planes.

- If multiple landing craft are equipped on the same ship, only one animation will be shown (the above table is sorted in priority order).
- A variation of the animation of the Ka-Tsu tanks
is also played against Atoll Nodes when applicable. - The animation of the Armed Armed Boats
is also played against PT-Imp when equiped. - These animations will be overridden by:
- Artillery spotting,
- Night cut-in.
